If we register a domain for 10 years and we remove 10 years from cycles;
Currently an error occurs for clients who has domain in this cycle.
I think better to consider this bug and make visible and invisible ticket for years in domain registeration cycle.
Is it possible to consider this in future versions not important when but consider if possible.
Maybe possible to add custom fields for invoice page like something you have for profiles or packages
Some User Custom fields like company register No and etc should be readonly after signup.
Please add this feature to User Custom Fields .
These fields are avaialble for editing only through signup and after that clients couldn't change something;
In new version of 6.4 domain list available only if "View List" selected from main page;
I think clients will ask where is our domains;
I think it's better to add "Domains" under Packages or new menu item.
I thought maybe this is something that could be considered as an option in this part;
I never thought your senario is wrong for upgrade but clients asking us a lot and we found they had other experience in other companies.
We can continue upgrarding manually when they opened a support...
